There are numerous lines overused, "even if it means my life!" - Find an anime that never says this! Most say it.

Bleach is a good example - an anime that has no apparent end, and you see them running out of ideas in form of fillers, Naruto, Inu Yasha, and even though Detective Conan (Case Closed) was one, but had few fillers because they were all stories in themselves and most all episodes cannot be considered fillers.

Men who run away from women or develop a "rash" from them just as they walk up to the guy or even talk.

Anime that try to be different by creating stupid hairstyles like you find in many CG-happy RPGs now, and Bleach is again, a good example.

An anime comedy that tries to be both funny and seriously romantic at the same time, it does not work!

Lastly, basically what Naruto Shippuden and Bleach attempt as far as trying to be different from other anime haha.

There is more, but I would have to look over all the previous anime I watched in the past.

I hate how the side characters/sub characters are almost never useful in an actual fight and have to wait til the main protagonist arrives to defeat the enemy

I hate when the main character is the 'perfect guy' character (mainly in Shoujo)...The types who have the looks, the brains, with girls hopping all over them, they have no flaws...totally nothing unique or interesting about them (Yamato, Hibari, etc)

I seriously hate long fights. A fight should take no more than 2-3 episode max, not 10-20...Short fights are much better (like the ones in Fairy Tail).

Lambo from 'Reborn'...I hate everything about that character, from the voice acting to the personality and the uselessness.

I hate it when they mix filler with cannon (they do that in Naruto). Like with Bleach atm I'm catching up and it's really easy to skip the fillers.
also when the good guy gets really badly beat up (like almost dead), they have a flashback and somehow manage to get to their feet and kill the other guy in one hit...
anything that is predictable and cliche. sadly Bleach has a lot of cliches.

I only have a problem when the characters look all alike and you can't tell who is who, or if your watching one and they look like another anime character and then you realize your watching the wrong one

What I hate the most is when the main Guy in a anime for Example: "To Love-Ru" Rito doesn't do anything to any of the girls... But in the other hand it better because I don't want it to end up like "School Days".
